on our broadcast tonight, the hostage crisis unfolding near the world's newest war. americans are among them. this standoff still developing tonight. the hoax that has everyone talking across the country, wondering what really happened to one of the biggest names in college sports who played for one of the most famous teams in all of sports. there's big news in the war on cancer. major progress to report tonight about how many lives are being saved and what's doing it. and dear abby. tonight we remember the woman who pretty much invented the business of giving advice. "nightly news" begins now. from nbc news world headquarters in new york, this is "nbc nightly news" with brian williams. good evening.

we have an unfolding american hostage situation overseas tonight. seemingly out of nowhere, over just the past few days, the eyes of the world have been focused on a region in africa where the french have chosen to go to war against islamist rebels. and then in what seemed like an immediate reaction to the french attacks, kidnappers grabbed some foreign workers at a bp oil facility in the sahara desert in nearby algeria. we know there were american hostages along with brits and others. we know there was a mission launched today to free them and kill their captors. we don't truly know tonight about casualties or how many americans might have made it out of there alive. we begin with nbc's stephanie gosk on what we do know. >> reporter: using tanks and helicopters, the algerian military launched an operation on their own, to retake the remote gas field from the militants and free the hostages. including at least three americans. algeria says it's over, but

details are few, and casualty reports vary widely from a few dead to dozens. u.s. officials are saying little about the operation or the american hostages. >> because of the fluidity and the fact that there is a lot of planning going on, i cannot give you any further details at this time. >> reporter: the militants attacked the sprawling gas facility in the remote sahara wednesday morning, taking dozens of foreign and algerian hostages. confirming algeria's operation to retake the facility, british prime minister david cameron did not sound hopeful. >> and i think we have to prepare ourselves for the possibility of bad news ahead. >> reporter: several hostages did manage to escape the militants. one called his family in ireland. >> it's like winning the lottery. getting him home again. i just feel so sorry for everybody else that's still there. >> reporter: the group claiming responsibility calls itself the signatories of blood brigade, founded by a former afghan gee

jihadist, mock tar mum tar bell mukhtar. kidnapping westerners and trading them for large ransoms. >> what does that say about their capabilities? >> they're very heavily armed, affiliates all over the place and supporters in europe and other francophone countries. if that isn't a concern, i don't know what is. >> reporter: a spokesman called the attack let obama administration for the conflict in the mali. french military forces have intervened to stop militants from taking over mali and making it a terrorist base. rohit kachroo is the only american network correspondent reporting from mali. >> people here have been flying the french flag to celebrate the military intervention. overwhelmingly, they want the islamists gone, and they welcome the operation to save them from life under an oppressive regime. >> reporter: tonight, france continues to press ahead in mali, bringing in more troops. the hostage drama in algeria is a reminder that islamic extremism knows no borders. stephanie gosk, nbc news, new

york. again, we know americans were among the hostages. the question is, was the u.s. military involved in the mission to free them and kill their captors. jim miklashevski covers the pentagon. he's with us from there tonight. jim, good evening. >> reporter: brian, from the very beginning, the u.s. offered the algerians overhead surveillance, gathered by u.s. satellites. today one unarmed u.s. military drone arrived in algeria to fly surveillance over the hostage site, but it was too late. the algerians have already begun their attack. the u.s. also offered algeria american combat forces, a rescue hostage team, but the algerians rejected the offer. they wanted to do this themselves. so in the end, the u.s. military had no direct role in this operation. tonight, administration officials say algeria did not inform the u.s. in advance of today's attack to attempt to rescue those hostages. but in the end it probably wouldn't have mattered.

according to one defense official, the algerians were in total control. brian. >> jim miklashevski at the pentagon. where we'll keep an eye on it. another big story today, big progress to report tonight in this country's specifically a dramatic drop in cancer death rates over the last 20 years. but the news from the american cancer society is not all good. it comes with a big warning about the next big risk. here with that our chief science correspondent, robert bazell. >> reporter: the report out today illustrates huge strides in the fight against cancer which kills one in four americans. the death rate down more than 20% in the last two decades is attributed to improved survival from the biggest killers, lung and colon cancer, for both men and women. breast cancer and women and prostate cancer. >> the public should be ecstatic we are seeing these kind of reductions but they need to realize the battle hasn't been one. >> reporter: experts emphasize the kind of death rate is not

due to the expensive new drugs we hear about. instead they point to people smoking less and early detection, especially for breast and colon cancer. still, this year, an estimated 1.6 million americans will be diagnosed with cancer, and more than 580,000 will die from it. according to the report, the death rate for melanoma, often caused by n exposure, is rising. and there is major concern about obesity, which affects many cancers, including liver, breast and colorectal cancer. >> over the next 10 to 15 years, it's indeed possible that the obesity epidemic will become the leading cause of cancer, surpassing tobacco abuse. >> reporter: and that could impact the gains we are seeing now. robert bazell, nbc news, new york. now to the bizarre story that broke nationwide last night involving sports and truth and lies and the internet age. at the center of this is a notre dame football player named manti te'o, a star linebacker, runner up for the heisman and a big

part of his dramatic back story was the death of his girlfriend of leukemia until this report surfaced that there was no girlfriend. she was an internet invention. te'o says he's the victim of a hoax. notre dame is standing behind him. there are still a whole lot of questions here. nbc's john yang is with us from south bend, indiana tonight. john, good evening. >> reporter: good evening, brian. today manti te'o was out of sight, he's a florida sports preparing for what he hopes is an nfl career. that as the story that is the centerpiece of his fairy tale final college year has collapsed around him. >> manti te'o! >> reporter: manti te'o was a college football hero, not just to the home crowd here at notre dame, but to fans across the country. hailed on the cover of "sports illustrated" as a star player who had triumphed over personal tragedy. in a single september day, he said, he lost both his grandmother and his girlfriend,

recently diagnosed with leukemia. in an interview posted in november on notre dame's youtube channel, he talked about the pain. >> when i lost my girlfriend and my grandma, that was possibly the hardest time of my life. >> reporter: the legend grew as te'o led notre dame over michigan, the day he says his girlfriend was buried. now it turns out his girlfriend never existed. as the website deadspin first reported, her identity was created in an elaborate deception. >> manti is the victim of that hoax. and he will carry that with him for a while. >> reporter: in a written statement, te'o said he communicated with the woman online and by phone. to realize that i was the victim of what was apparently someone's sick joke and constant lies was and is painful and humiliating. while he told others he had discovered the deception on december 6th, he still talked about his ill-fated girlfriend at the heisman trophy ceremony two days later. >> i'll never forget the time i

found out my girlfriend passed away. >> reporter: and he didn't tell notre dame officials until december 26th, 20 days afterward. the school hired private investigators and got the final report detailing the hoax on january 4th, three days before losing the national championship game to alabama. >> it's not the kind of publicity that notre dame is looking for. not the kind of publicity that te'o was looking for. and so it's understandable that they kept a lid on this as long as they possibly could. >> reporter: on campus today, students' admiration hasn't dimmed. >> it's not just like, oh, yeah, he's like a football player. it's like he's a fantastic person. >> he just kind of represents what this campus is all about. >> reporter: even te'o's admirers here on campus say they would like to hear him tell a more detailed version of his side of the story as they try to find the big, unanswered question in this hoax. why. brian? >> john yang, headquarters of the fighting irish in south bend tonight, thanks. hours before his big confessional interview with

oprah, set to air tonight, the international olympic committee has asked lance armstrong to send back the bronze medal he won at the 2000 olympic games in sydney. he was stripped of his seven tour de france championships last year by the u.s. anti-doping agency. the head of the anti doping body said today armstrong should have already returned the olympic medal without having to be asked. it's been nearly six months now since a gunman opened fire in the packed movie theater in aurora, colorado, killing 12 people, wounding 58 hours. tonight the theater is reopening for the first time. private ceremony for victims and first responders. it's not without controversy. it's being boycotted by some of the victims' families who say it's insensitive to reopen the theater at all. and following the aurora massacre and the m in newtown, connecticut, the president is now trying to build public support for his sweeping plan to curb gun violence. director and chieft. white house correspondent, chuck

todd, has our brand new polling numbers about how americans are feeling about gun laws. >> reporter: a day after the president unveiled his recommendations to curb gun violence -- >> this is our first task as a society. keeping our children safe. >> reporter: the new nbc news "wall street journal" poll shows 56% of americans do want stricter gun laws. 7% say they're too strict now. and 35% want no changes. 20 years ago, the last time real changes were debated, a full two-thirds of americans wanted stricter gun laws. this time, the public appears to be looking at the complex reasons behind the spade of mass shootings. a large majority said they believed lack of parental involvement with their children, inadequate mental health care and violent video games all contributed more to the gruesome shootings of the past two years than access to guns. and while the president talked a lot about mental health issues yesterday -- >> we will make sure mental health professionals know their options for reporting threats of violence.

>> reporter: he never once mentioned parental involvement. [ gunshot ] >> reporter: so really understand the complexities of the gun debate in america, look who owns guns. our polls show that 41% of all households have a gun. in rural america, 61%. in urban homes, 29%. and our poll shows a dramatic political divide. 55% of republicans say they have guns. 27% of democrats do. and while the national rifle association has been a lightning rod, 41% in our poll said they have a positive view of the organization. 34% a negative one. among gun owners, the nra's positive rating is 62%. among nongun owners, 25%. >> we're powerful to the extent that we are because there are millions and millions of americans who truly care about second amendment issues. >> reporter: of course, this was part of an extensive look we did in this poll on the president, where he stands going into the second term, as well as all of washington. and it won't surprise you, brian, to find out if it's possible, americans have grown

more pessimistic about its leaders here in d.c., and worse, they think washington is hurting the economy. the whole poll is on our website right now. nbcnews.com. >> boy, those numbers didn't have much far further to go. chuck todd in our d.c. newsroom tonight. thanks for all of it. weather is making news tonight. a very large winter storm system has left quite a bit of snow on the ground from the deep south, and we're talking about mississippi, alabama, rare snow on the ground there, to the mid atlantic tonight. systems moving fast, but the snowfall where it's falling is heavy and intense. there is one storm-related death to report. thousands are without power. you're looking at a live picture of the scene outside richmond right now. they could get up to 6 inches there tonight with a rain/snow mix, hazardous travel expected tonight, right up through the carolinas. it will all move out to sea by tomorrow. it will knick the jersey shore and at least long island on its way out. still ahead as our broadcast continues, the mystery coming ashore.

"dear abby" became a trusted household name, reads by tense of millions in hundreds of newspapers worldwide. >> i get about 300 letters a day that sound just like this one. dear abby, i'm a girl of 14 and i like a boy of 15. >> reporter: even presidents took note of her popularity. >> abby, thank you. >> thank you, mr. president. >> she wasn't a doctor, physician. she was just a woman from iowa who had great, good common sense. >> reporter: phillips was also on the radio for 12 years, an author to six books. famous for one-liners. "dear abby, between you and me,

i think the people who write to you are either morons or they're just plained stupid." signed henry. she replied, "dear henry, which are you?" some confused her with her twin sister, ann landers, also an advice columnist. both helped raise awareness about health issues. in 2000, phillips started to share the column with her daughter. soon after, it was revealed phillips had alzheimer's. today, her daughter jeannie who took over the column said my mother leaves very high heels to fill with a legacy of compassion. asked years ago, has it been a lot of work? not really, phillips said, it's only work if you would rather be doing something else. rehema ellis, nbc news, new york. and that's our broadcast on our thursday night. thank you for being here with us. don't forget, "rock center" tonight will have an exclusive interview with the most famous scientologist to ever leave the church, and a book that
